Where there two variations of Model 510 Packers vs. Colts

[murraycraw1967]

Good morning:

I read on a seller's web page that there were two variants of Tudor Model 510 (Packers vs. Colts).  He mentions the 1967/68 (with Big Men) variant and then a 1969 (Hog Legs) version.  He mentioned slight differences without going into details other than the different player style and different team logos on the scoreboard flags.

My questions are were there two variants of the game and if so how can you tell which is the 1967 or the 1969 version?

I found no mention of a second variant in Unforgettable Buzz, other than the slight change in the players.  The photo on the exterior box does have a variation of the logos (maybe earlier Saints) on the scoreboard flags but not on the actual game scoreboard.

Thanks in advance for any input.
